• Stock LT1 Injectors, Lingenfelter Big Bore HPDI pump, 91 octane + 70%water/30%meth injection - 620 RWHP
• Stock LT1 Injectors, Lingenfelter Big Bore HPDI pump, MS109 + 50%water/50%meth injection - 688 RWHP
• LT4 Injectors, Lingenfelter Big Bore HPDI pump, ZL1 in-tank pump, MS109 + 70%water/30%meth injection - 694 RWHP

And that's where I left it last Saturday, didn't have the right size belt to go with a smaller pulley, so picked one up in Sunday and will be looking for more power later this week.
It also might be time to consider adding some more exhaust components. I'm not looking to lose the stock cats, but I may add the shorty headers I bought a couple months back to see if they have any benefit.

Looking forward to your results as I want to do the LT4 upgrade to my SS and seems the fuel may be limited to 600rwhp with stock fueling system...
